More Information
Summary:•BHJ-based organic solar cells are realized on nanoscale textured glass substrates.•The nanoscale SWS exhibited excellent antireflective property.•The BHJ-based organic solar cells incorporating SWS can harness more solar power.•The PCE of the SWS integrated organic solar cell was relatively improved by 7.2%. Bulk heterojunction (BHJ)-based organic solar cells realized on glass substrates incorporating antireflective nanoscale subwavelength structures (SWSs) can harness more solar power, leading to greater electrical output power. The power conversion efficiency of the SWS integrated BHJ-based organic solar cell was relatively improved by 7.2% compared with that of conventional solar cell without SWS.
